Ram Watch is a tool originally written for GENS rerecording. It was ported to FCEUX in version 2.1.2. This dialog has also been ported to SNES9x-rr, Desmume, PCEjin, VBA-rr, PCSX-rr, Yabause, and FBA-rr.
It is designed to filter ram values just like in the Cheat Search dialog. However, it features many options that are lacking in the Cheat Search dialog. Among these are search undo, search preview, a modulus filter, a data size option, signed/unsigned/hex options, autosearch, and several more compare by options.
Documentation on this dialog can be found on TASVideos here.
